// This Arduino example demonstrates bidirectional operation of a | |
// 28BYJ-48, which is readily available on eBay for $4.25 inc shipping, | |
// using a ULN2003 interface board to drive the stepper. The 28BYJ-48 | |
// motor is a 4-phase, 8-beat motor, geared down by a factor of 64. One | |
// bipolar winding is on motor pins 1,3 and the other on motor pins 2,4. | |
// Refer to the manufacturer's documentation of Changzhou Fulling | |
// Motor Co., Ltd., among others. The step angle is 5.625/64 and the | |
// operating Frequency is 100pps. Current draw is 92mA. | |
// Vin w USB power is 4.5v too slow for testing use 5v pin. | |
